Refer to the Installation chapter in this guide for connecting power to
your BM85. Connect the source of AC or DC power to the BM85. Do
not turn on the power to the BM85 until you set the Modbus port
configuration switches and connect the configuration terminal. The
switch settings will be sensed when power is applied.
